I know im gonna get flamed for this, but my experience is, that its not very smart to go for the lowest bids when buying either 1. Monitor 2. Motherboard. If you have any concerns for longevity, features or factory guarantees that is..
My personal opinion is, that its quite easy to find "affordable" but quality products, if you forget straight number comparisons and spend a few days looking for roundups and guides. I also have certain manufacturers that i wouldn't spend a dime on anymore..They include anything coming from the Korea, Samtronics, Samsung to name a few..Then there is the LG, which usually manufactures under lease from piss poor brands like Philips..Altough LG will use every quality for quantity trick to get their price tags even lower.
I currently have 1 CRT and 1 LCD, both 19" from ViewSonic, manufacturer which seems to get quite good reviews mostly. They were in the lower medium price range when i bought them..
